Thorngrasp

Choose a target within range. Thorns protrude from the ground and grasp the target. The target must make a Dexterity saving throw. On a failed save, the target takes 1d8 necrotic damage plus 1d8 piercing damage and is restrained until the end of its next turn. On a successful save, the damage is halved and the target is not restrained.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the target is restrained for 1 minute. At the end of each of its turns, the target can repeat the saving throw, ending the effect on itself on a successful save.
